[PATCH v4 00/19] Allow vendor drivers to propose their own timings

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

As raised by Rickard, certain chips like Toshiba/Kioxia
TH58NVG2S3HBAI4 are not ONFI compliant and because of that, work at a
very slow pace. This chip in particular supports running at a pace
"close" to ONFI mode 4.

This series provides a way to manufacturer drivers to propose a data
interface to the core with a very simple interface (see patch 19/19).

Cheers,
Miquèl

Changes since v3:
* Took Rickard patch based on my previous proposals over Github and
  tweaked a few more things:
  - Added a "generic" helper to fallback on slower ONFI modes when the
    proposed interface is not supported by the controller.
  - Fixed more kdoc.
  - Simplified the vendor driver side by providing additional helpers.
* Tweaked a little bit Rickard patch to fit the latest changes.
